Mila Kunis wants natural birth

The 'Black Swan' actress is expecting her first child with fiance Ashton Kutcher and has vowed not to have a pain-numbing epidural injection to ease her labor, which may take place at home.

Speaking about her pregnancy for the first time, she said: "We thought about a home birth, we watched a couple of documentaries and spoke to some midwifes and people, and realized our hospital have the midwives and doulas who can do that.

"I'm going to do it as natural as I can, No epidural, I'm crazy, right. But I wanted this! I did this to myself, I might as well do it right. Well, I did have a little help..."

The brunette beauty also admitted Ashton has been so prepared during her pregnancy, he even stocked up on "goofy" foods he thought she might experience cravings for.

She told TV talk show host Ellen DeGeneres: "He assumed that I was gonna have goofy cravings, so he stocked our secondary fridge with weird food. Just like pickles, and sauerkraut, or like anchovies, and ice creams...just in case at one point during this pregnancy I'd be like I really want something.

"And it happened last week, I was like, 'Oh my God, I need a pickle.' It was just the weirdest thing.

"I needed this pickle and he was like, 'Hold on a second' and disappeared in the backyard and came back with the most amazing dill pickle of all time."

Ashton, 36, is also taking Russian lessons so he can communicate with the baby in Ukranian-born Mila's native tongue.

She said: "He's been taking classes for six months, he does it twice a week, a woman comes to the house and gives him lessons."

And the 30-year-old star admitted she and the 'Two and a Half Men' star - who was previously married to Demi Moore - were engaged for some time before it became public knowledge.

She said: "We were able to keep this private for two months without anybody knowing, I think everybody assumed we were engaged for so long that I was wearing the ring in public for two months and nobody commented on a single photograph."
